MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 308,784, dated December 2, 1884-.

- and claimed hereinafter, for converting a vibrating motion into a reciprocating motion. I11 the accompanying drawings, Figure 1 1s a perspective diagram illustrating the operating parts of the device; Fig. 2, a sectional plan showing the face of the wheel; Fig. 3, a vertical section on the line 1 2, Fig. 2, the wheel being in elevation; and Fig. 4, a diagram drawn to a reduced scale and showing a modification of the invention.

A is a shaft to which a vibrating motion is supposed to be imparted, and B a flexible strip of metal to which a reciprocating motion is to be imparted through the medium of the wheel D, secured to the said shaft A. The wheel fits snugly into the circular recess of a fixed casing, G, and is confined thereto by a removable cap, 6. Although the wheel must fit accurately within the circular recess of the case G, and between the bottom of the recess and the cap, the fit must be such as to permit the wheel to be vibrated freely and without undue friction. The periphery of the wheel is grooved to admit the flexible strip B, which is secured to the said periphcry in the present instance at the point 50, Fig. 2, the strip extending through a curved passage, m, in the casing and out through a guiding-slot at the projecting end of the said casing. The object is to impart a long and steady reciprocating motion to the outer portion of the strip by alternately winding the inner portion partly round and unwinding it from the wheel. If the wheel be twelve inches in diameter, for instance, and be vibrating to the extent of one-third of a revolution, the outer end of the strip will have a movement of about twelve inches in a straight course; but the wheel may be turned nearly to the extent of a complete revolution and back again, in which case the movement of the strip will approximate three feet.

As an example of the uses to which this Application filed September 8, 1884. (No model.)

mechanical movement may be applied, I may refer to a warp drawing machine in which a hooked needle with a long reciprocating movement was required, and in which it was essential'that the movement should be a steady one. The strip was converted into a needle by forming at its extreme outer end the hook 1 (Shown in Figs. 1 and 3.) It was found in practice that, although the hook had a long distance to move outward and retiirn, it was much more steady during this movement and during the act of reversing than appliances which had been previously used for reciprocating a hooked needle.

Fixed guidesy, one of which is shown in Fig;

course, the guides being placed at such a distance apart as to prevent the bending of the portion of the strip which may be outside the casing. It may be further stated that in this application of my invention the wheel was twelve inches in diameter, and the dimensions of the strip in cross-section were a quarter of an inch wide by one-sixteenth of an inch thick, and it was made of steel.

My invention admits of application to all uses in which a reciprocating strip having a comparatively light duty to perform would be available.

It is not essential that the periphery of the wheel. D should be grooved; but a groove is preferable for the lodginent of the strip. The passage m should be made on a comparatively gentle curve, so that no very abrupt bending of the strip can take place as it is projected from the casing on moving the wheel in one ICC cry of the said. wheel are combined with a to this specification in the presence of two subfixed casing containing the said wheel, and. scribing witnesses. having a passage through which the strip may be projected outward. from the casing and GEORGE MOORE 5 Withdrawn into the same, all substantially a Witnesses:
